From the Society of Vertebrate Paleontology this covers the indexed published literature of vertebrate paleontology from 1509-1993. "The BFV Online provides interactive access to the SVP's 'Bibliography of Fossil Vertebrates' series. Using the BFV Online, users can specify a search criterion, and receive a formatted list of matching literature references. Results will appear in a new window (users that have activated pop-up blocking in their browser may need to adjust their settings for this to work properly). Queries are formed like taxon = 'Tyrannosaurus'. Detailed instructions are available for writing queries, including complex Boolean statements and the use of pattern-matching."

"This site, directed by John van Wyhe at the University of Cambridge, began in 2002 to assemble all of Darwin’s published and unpublished writings.  The result is the largest Darwin resource ever created, with 75,914 pages of searchable text and 184,561 images.  With the 150^th anniversary of the publication of Origin of Species in 2009, the 70 million users who already visit the site should swell drastically."

"Darwin's correspondence provides us with an invaluable source of information, not only about his own intellectual development and social network, but about Victorian science and society in general. They provide a remarkably complete picture of the development of his thinking, throwing light on his early formative years and the years of the voyage of the Beagle, on the period which led up to the publication of The Origin of Species and the subsequent heated debates."

"Microbial Life (ML) is a valuable addition to microbial ecology Web sites in the way it explains the wide variety of research areas and projects in the field. Funded by the National Science Foundation, ML is the product of collaboration between the Woods Hole Marine Biology Laboratory in Massachusetts and Montana State University in Bozeman, Montana. Other sites are geared to either much younger students or individuals already involved in the field. ML targets a broader audience: the general public, high school and undergraduate students, and teachers who need accurate, current information on microbial ecology without being overwhelmed by the complexity of the information presented.

Pages load quickly and exhibit a good balance between clear, readable text and excellent, informative micrographs. Major sections of this extremely well-organized site provide information about extremophiles and marine microbes, as well as the habitats of these intensely studied microbes. A section on microbial observatories lists numerous research sites around the world along with research findings and pictures from the research groups involved. ML serves as an excellent jumping-off point for those who wish to delve more deeply into this area of research. Users will also benefit from a section on research methodologies in microbial ecology. Brief, informative pages cover the major research methods in the field, with links to a variety of educational sites where more detailed information can be found. Teachers will find a section on teaching methods, sample teaching topics and tips, and case studies, as well as an exhaustive collection of links to a multitude of online sources including image collections and databases. Overall, this excellent, resource-rich site should prove to be an invaluable resource to anyone needing current information about microbial ecology." from Choice, June 2009.

"The stated goals and target audiences for The Paleobiology Database range from general, educating the interested public and summarizing paleobiological literature for students and professionals, to specific, providing taxonomic and stratigraphic information about fossil plants and animals, with emphasis on analyses of mass extinctions and other aspects of historical biodiversity. Begun in 2000, the site currently archives 17 downloadable taxon-centered databases, ranging from protozoa to mammals. Included is J. Sepkoski's compendium of all fossil marine animal families and genera through geologic time that first revealed the extent of mass extinctions. The compendium is continuously updated, facilitating new interpretations of the evolutionary history of marine biodiversity. The databases are data-rich with documented systematic revisions, but by themselves are rather cumbersome and lack much explanation of their formats. They are directly useful mainly to specialists in the respective groups. However, the site provides a broad array of search and analysis interfaces, complex but straightforward, user-friendly tools that permit novices and professional paleontologists to effectively access the information in the databases.

Search functions allow users to access data in separate categories such as collection records, classification, stratigraphy, and publications. This covers both the broad swath of Earth history and biodiversity, and detailed classification of taxa to species and of strata to subepoch. Analysis functions lead to interactive components that provide (as examples) diversity curves based on the user's taxonomic and temporal specifications, generated from the databases mentioned. Geographic distribution records for taxa and strata can be plotted on annotated maps that also show contemporary sea/land boundaries." (from Choice, January 2009)

"The Plant Evolution Timeline was developed by Nicola Peart and Ben Roberts as part of the UK's Ensemble: Semantic Technologies for the Enhancement of Case Based Learning project, and created using a modified version of the open software from the MIT SIMILE/Timeplot project. It is a "cut-down version" of a tool used in teaching plant evolution at the University of Cambridge. The plant evolution time line is separated into two panels, an upper panel that plots seven abiotic (one biotic) factors and a lower panel that plots nine biotic factors that can be turned on and off in various combinations against geologic time.

Users can click on the geologic eras and periods, and the panel will zoom in on the plotted data in each panel for that particular time period. When clicking on the geologic era or period, the site also displays an illustration of the continental positions at that time. The Timeline integrates a variety of key information, and this is an excellent teaching graphic to correlate changes in abiotic and biotic factors through time. The simplicity and clarity with which the data are presented also make the site student- and user-friendly and make for a very clean and interactive graphic to use in the classroom. The one drawback of the data being plotted is that it does not present competing interpretations of a particular biotic or abiotic parameter; however, the graphic can be used to initiate these classroom discussions. This is a useful Web site for presenting integrated data to students on evolutionary change through time, and is an excellent instructional resource for teachers of grades 8-12 through upper-level undergraduate courses. Designed to work with Firefox 2.0." - M. S. Zavada, East Tennessee State University, from Choice Online
